Mobility Flashcards
1
Q
Bones: Three Layers
A
- Periosteum
- Compact bone
- Medullary Canal: Red and yellow bone marrow & fat cells
2
Q
Bone surroundings
A
Muscles:
- Tendons- muscle to bone
- Ligaments- bone to bone
3
Q
Sprains
A
- Trauma to a joint
- Tearing of ligaments
- Often due to twisting injury
4
Q
Strains
A
- Trauma to muscle or tendon
- Often due to excessive stretching or overexertion
5
Q
S&S of sprains and strains
A
- Swelling/edema; tiny hemorrhages occur within the disrupted tissues
- Superficial bruising or hemarthrosis (bleeding into a joint)
- Pain; Sprains usually more painful D/T the area having large numbers of nerve endings
- Limitation of movement
6
Q
Treatment of Sprains/Strains
A
- Rest
- Ice (v muscle spasms) - no longer than 20 min
- Compression
- Elevate
- Movement
- Anti-inflammatory drugs- slow down bone healing
- Go to heat after 24 hours (20 min at a time)- heat helps body absorb lactic acid and get away from injury
7
Q
Coban
A
Bandage with more stretchiness and sticks to itself- (start at bottom and work your way up)
8
Q
Fractures (Causes)
A
- Trauma: falls, accidents
- Weak bones
- Movement disorders
- Long term steroid use: Osteoarthritis, total hip/knee prematurely, demineralization, and could ^ glucose levels
9
Q
Pathophysiology of Fractures
A
- Force to bone & muscle causes break in structure of bone
- Nearby blood vessels break causing bleeding into area, creating swelling & pain
- Nearby muscles go into spasm, causing more bleeding/pain & swelling
- Spasms may cause fractured ends to move, causing more bleeding and swelling (even if you don’t tear muscles; If you don’t stop spasms. could cause misalignment
10
Q
S&S of fractures
A
-Edema
-Pain
-Muscle spasms
-Deformity
-Ecchymosis
-Loss of function
-Crepitation (feels like bubble wrap)
-Numbness
-Hypovolemic shock
(S&S are mostly the same for sprain, strain, & fracture so you can only tell by an x-ray)
11
Q
Diagnostic Tests
A
X-rays
CAT scan- no need unless its in your back
MRI- no need unless its in your back
Bone Scan- nuclear med scan; injected with nuclear stuff and start looking for uptake in x-ray
12
Q
Stages of Healing
A
- Fracture hematoma
- Granulation tissue
- Callus
- Ossification- when cast comes off (4-6 weeks); teach pt. it’s still not completely healed
- Consolidation
- Remodeling; about 6 months to remodel
13
Q
Complications with fractures: Delayed Union
A
healing does not occur within normal expected time frame
14
Q
Complications with fractures: Non-union
A
Fracture never heals; two ends of bone do not fuse together
15
Q
Complications with fractures: Infection
A
Can be seen in open fractures or any fracture with surgical intervention; can lead to delayed union or non-union
16
Q
Complications with fractures: Avascular Necrosis
A
An interruption in blood supply to bony tissue, which results in death of bone (most common with steroid use
S&S; pain and decreased sensation
17
Q
Complications with fractures: Compartment syndrome
A
- Increase in tissue pressure which results in a v blood supply (swelling, edema)-impaired tissue perfusion
1. internal pressure
2. external pressure
3. pressure on nerves, blood vessels
4. decreased blood flow to injury
5. increased pressure on nerves
6. pain/immobility
18
Q
S&S of compartment syndrome
A
- Progressively increased pain (not relieved by narcotics)
- loss of sensation
- loss of function
- pale, cool skin
- decreased or absent pulses
19
Q
Treatment of compartment syndrome
A
Fix cause; stop bleeding or remove tight cast
-Fasiotomy: make incision into fascia to open up compartment space & decrease pressure
(can lead to tissue death and amputation)
-If you have any idea that it’s compartment syndrome, put pt. on NPO to get ready for OR
20
Q
Complications with fractures: Venous Thrombosis
A
- D/T prolonged bedrest & immobility
- Prevent with TED hose, SCD (assess pressure (40-45), inflating & deflating), ROM exercises, daily ASA or Heparin or Lovenox
21
Q
Complications with fractures: Fat embolism
A
- just as deadly as venous thrombosis if not more
- condition in which fat globules are released from the marrow of the broken bone into the blood stream
- Occurs in first 48 hours after injury
- Seen in big fractures
22
Q
Fat Embolism (where it occurs)
A
- Fractures from the long bones, ribs, tibia, pelvis, joint replacement, & spinal fusions most often are the cause
- Migrates to lungs, brain, heart, or kidneys
- Symptoms depend on location where fat embolism traveled
- *Prevention is important because it’s hard to treat
23
Q
Fat Embolism: treatment
A
- Hydration
- correction of acid/base
- replacement of blood loss
- Immobilization of fracture until stabilized
- respiratory support: O2, mechanical ventilation if ARDS develops
24
Q
Fat Embolism: S&S
A
Confusion, ^RR, crackles (fluid in lungs), Petechia (really small pinpoint rash- not raised, purplish red)
25
Fracture Management: First Aid
- Splint in position found
- Decrease movement
- Elevate
- Ice
26
Fracture Management: Closed Reduction
Bones are manually moved into position
27
Fracture Management: Open Reduction
Incision made at fracture site so bones can be internally put into alignment (OR; plates and screws)
28
Fracture Management: Immobilization (3 ways to do this:)
- Process of keeping the bone ends together
1. External fixation
2. Internal fixation
3. Traction
29
Fracture Management: Traction- 2 types
1. Skin: treatment attached to skin directly- wrap & have pulley's & weights
2. Skeletal: Metal pins placed in bone distal to fracture, pin attached to metal bow & weights added to pull on bone to keep alignment (infection prone)
30
Casts (how made)
Plaster cast material is immersed in warm water & wrapped around, soft, thick, cast padding
-Synthetic material is immersed in cool water
-Plaster & fiber glass hardens within 15 min
-Cannot weight bear for 24-72 hours
(x-ray after cast is applied)
31
Casts: Handling and care of a fresh cast
- Never cover a fresh cast with a blanket because air cannot circulate & heat builds up as it dries and sets (cast gives off heat and heat needs to escape)
- Handle with palms of hands until dry
- Synthetic casts are lightweight and waterproof (pads arent waterproof)
- Splint is applied when a lot of edema is expected
32
Casts: Assessing
- Assess edges for any pressure on skin
- Use 5 P's to assess area distal to cast (pain, pallor, paralysis, paresthesia, pulselessness)
- OR assess w/ CMS- circulation, movement, sensation
- If core is casted, assessment of breathing patterns, & bladder and bowel function are necessary
(cap refill, movement, temp, color)-to make sure cast isn't too tight
33
Casts: Teaching
- Encourage patient to actively move non-immobilized joints to prevent stiffness & contractures
- After casting, extremity should be elevated with pillows about heart level for first 24 hours to decrease edema
34
Slings (assessment, pt. teaching)
- If short term, flex elbow are 80 degrees (hand slightly higher than elbow)
- Thumb should be facing upward or inward
- Inspect axilla for skin breakdown
- Check for undue pressure around neck
- Movement of fingers should be encouraged to enhance circulation & decrease edema
35
Crutches (pt. teaching) (NOT ON EXAM 3)
Three types: Axillary, Lofstrand, & Platform
* Weight is borne by the muscles of the shoulder girdle & upper extremities
- PT usually measures for crutch placement
- Weight of body should be borne by the arms, not axillae (overtime could cause numbness in brachial plexus)
- Maintain posture
- Each step should be confortable stride
36
Crutches (Assessment & instructions) (NOT ON EXAM 3)
- Inspect crutch tips regularly
- Wear rubber sole shoes
* Going down stairs, move crutch and affected leg first
* Going up stairs, place weight on crutches & move unaffected leg onto step
- Chairs that have armrests & are supported by a wall are safest for transfer in and out of chair
- When getting into or out of a chair, the pt. hold the crutches on the affected side
37
What are External Fixators?
- Metal pins inserted into the bone proximal & distal to fracture
- The pins are then attached together with external rods in order to keep the extremity aligned & completely immobile
* Most often used for nonunion or complex fractures with extensive soft tissue damage
* Long term
38
External Fixators (Pin care)
Risk for infection is high because microorganisms can enter bone around the pin insertion sites (check temp. every morning)
- Meticulous pin care necessary
- Pin care done 2x/day with either Chlorahexidine or half-strength hydrogen peroxide with normal saline
39
External Fixators (S&S of nerve damage)
*If numbness, tingling, severe pain, etc post-op, tell physician immediately (nerves may have been drilled through
40
Internal Fixation (ORIF) (what is it, alignment, post-op)
- Use of pins, plates, & screws, which are surgically inserted into the bone, after the fracture is reduced manually
- Alignment is verified with the use of fluoroscopy (continuous x-ray machine during procedure) during surgery
* Usually have a splint on post-op and first dressing is done by surgery
41
Bone Nailing
* Used in femurs
| - A lot of post-op pain
42
compound fractures
AKA open fractures (skin broken with bone protruding out)
- Wound culture done
- Requires surgical intervention
43
Osteomyelitis (S&S)
(Bone infection)
- Temperature rise
- swelling
- redness that spreads
- uncontrolled pain
- ^ in drainage, and then start to see drainage change
- ^WBC
44
Osteomyelitis (treatment)
Antibiotics- know if working if symptoms go down
45
Traction
A steady pull by weights to keep the bone ends in position
-Decreases likelihood of non-union
-decreases muscle spasms
-traction is now used as a hold over until you're in surgery
(Assess pedal pulses & cap refill when you put boot on)
**Assess boots and weights every 8 hours
46
Skin Traction
- may be used first 24-48 hours until ORIF can be performed
- Tape, boot, or splint is applied directly to the skin
- Weight is 5-10 pounds
- EX- buck russels, Bryant's, Girdle, and head halter
* Weight is attached slowly
47
Skeletal Traction
Pin inserted through bone and then attached to weights using metal bows
-Weight ranges from 5-45 pounds
48
Traction Care
```
T- emperature
R- opes
A- lignment
C- irculation
T- ype and location of fracture
I- ncrease fluid intake
O- verhead trapeze
N- o weight on floor
```
- Forces must be pulling in opposite direction to prevent pt. from sliding to the end or side of the bed
* need 4 people to assist when moving pt. (make sure weights stay in place
49
Effects of Immobility: Musculoskeletal
- Bones demineralize without weight bearing activity
- Muscles atrophy losing their normal strength and function
* Contractures form, limiting joint mobility (ROM)
- Collagen tissues at the joint become ankylosed (solid, hard)
50
Effects of Immobility: Circulation
- v cardiac reserve (intercostals and heart deconditioned)
- Increased use of valsalva maneuver
- Orthostatic hypotension
- Venous Dilation & stasis (v venous pooling)

51
Lovanox
Inject WITH bubble (prevent drug from coming back up)- make sure bubble is at top
* anticoagulant therapy indicated to help reduce the risk of developing DVT
52
Effects of Immobility: Aeration
- v respiratory movements
- pooling of pulmonary secretions
- atelectasis
- hypostatic pneumonia
53
Effects of Immobility: Nutrition
- v metabolic rate
- negative nitrogen balance
- change in intake habits
- negative Ca balance
- bone demineralization
54
Effects of Immobility: Elimination GU
- urinary stasis
- urinary retention
- UTI
- Renal calculi
55
Effects of Immobility: Elimination GI

57
Effects of Immobility: Anxiety
- v self esteem
- altered perception of time
- v ability to problem solve and make decisions
- feelings of loss of control
- v social and motor development in children
58
Immobility assessment
-To assess for activity tolerance look at HR, strength, & rhythm;
respiratory rate, depth, and rhythm;
& BP
-get baseline during activity, immediately after activity, and 5 min after activity
59
Immobility assessment: the activity should be stopped if the following are noticed
- sudden facial pallor
- feelings of dizziness of weakness
- changes in LOC
- diastolic BP change of 10 mmHG or more

Guillotine or open amputation
leaves the bony end open - not open permanently (for areas that are bleeding)
71
Post-op teaching for amputations: Purpose of Cast:
1. v edema
2, prevent hip and knee contractures (ROM)
3. Help shape the stump for prosthetics later on
72
Post-op teaching for amputations: Positioning
1. elevate 24-48 hours
2. keep flat after 24 hours
3. prone positioning- to prevent hip contractures

96
Laser discectomy
Outpatient procedure
The laser is used on the herniated portion of the disc
-not any better than any other way if its a big herniation
-don't have to chip away at the bone
-pt goes home same day and not much post op pain
-ideal for small herniation
97
What is a Spinal Fusion
- used for unstable spinal areas by creating a contiguous vertebrae with a none graft
